《课程标准(2011年版)》指出:“几何直观主要是指利用图形描述和分析问题。借助几何直观可以把复杂的数学问题变得简明、形象,有助于探索解决问题的思路,预测结果。”由此可见,几何直观在小学数学学习中有着极其重要的作用,它沟通了儿童形象思维与数学抽象逻辑之间的联系,使复杂的数学问题直观化,抽象的数量关系形象化,实现了问题与图形之间的转化,有助于探索解决问题的有效策略。那么在小学阶段,应如何加强学生几何直观能力的培养呢?
Curriculum Standard (2011 Edition) states: Geometry intuition mainly refers to the use of graphical description and analysis of the problem with geometric intuition can be complex mathematical problems become concise, the image helps to explore the problem solving ideas, prediction results Thus, the geometric intuition plays an extremely important role in primary school mathematics learning. It communicates the connection between children’s image thinking and mathematical abstract logic, visualizes complicated mathematical problems, visualizes the quantitative relationship between abstract numbers, Realize the transformation between the problem and the graph, and help to explore effective strategies to solve the problem. So in primary school, how to strengthen students’ ability to cultivate the geometric intuition?
